The Differences Between Sedimentary, Igneous, and Metamorphic Rocks…
Introduction. The Earth's crust is a dynamic system that has evolved over millions of years, giving rise to different types of rocks. These rocks—sedimentary, igneous, and metamorphic—form the foundation of Earth's geology and hold clues to its past.Each rock type is defined by its formation process, composition, and texture, which are directly related to the …

rock, in geology, naturally occurring and coherent aggregate of one or more minerals. Such aggregates constitute the basic unit of which the solid Earth is composed and typically form recognizable and mappable volumes. Rocks are commonly divided into three major classes according to the processes that resulted in their formation. These classes are (1) …

Sedimentary Rocks
They are also called detrital sedimentary rocks and are formed from pieces of preexisting rocks loosed by weathering. The loosened rocks are then transported to some depression where the sediments are trapped. If it is buried deep, it becomes compacted and cemented, forming sedimentary rock. Clastic sedimentary rock m…

Sedimentary Rocks
The three types of sedimentary rocks, based on their formation process, are clastic, chemical, and organic. Sedimentary rocks are one of the three major types of rocks found on Earth, alongside igneous and metamorphic rocks.They are unique in their formation process, which involves the deposition, compaction, and cementation of sediment.

Sedimentary Rocks: Types, Formation & Uses
Sedimentary Rocks are defined as those formed by the consolidation of sediments. The various weathering agencies wear down the pre-existing rocks. The weathered products called sediments are carried to water bodies like lakes and oceans by the rivers, where they accumulate and later by compaction and cementation from sedimentary or secondary rocks.

Introduction to Rocks
There are two major groups of sedimentary rocks: 1) siliciclastic and 2) chemical and organic. Visible layering is common in sedimentary rocks. Most fossils are found in sedimentary rocks; exceptions are specimens found in metamorphic rocks that were once sedimentary (e.g., fossil shells in marble) or those found in ice (e.g., remains of mammoths).
